Abstract:
The present investigation entitled “Effect of plant growth regulators on growth and flowering of China aster (Callistephus chinensis L.) cv. Phule ganesh pink’’ was carried out during the year 2020-21 at Department of Floriculture and Landscape Architecture, Pt. Kishori Lal Shukla College of Horticulture and Research Station, Rajnandgaon. The growth regulators used were Gibberellic acid (150, 250, 350, 450 ppm), Naphthalene acetic acid (50, 100, 150, 200 ppm) and Salicylic acid (50, 100, 150, 200 ppm). The result obtained that the Minimum number of days to first flower bud initiation (64.87 days) and days to opening of flower from bud appearance (8.07 days) were noted in GA3 150 ppm and days to 50% flowering (82.47 days) was recorded in GA3 250 ppm and longest blooming period (68.80 days) was noted in GA3 150 ppm. Highest individual flower weight (3.90 g), Flower yield plant-1 (161.21 g), and highest yield of flower per hectare (164.21 q.) were noted under GA3 150 ppm. Maximum flower diameter (7.25 cm), stalk length (15.15 cm) was noted in GA3 250 ppm. In research, control was reported minimum for every trait from different concentrated PGRs taken in the investigation.
